Factoring and Greatest Common Factors

This video tutorial from YourTeacher.com introduces a factoring problem that cannot be solved using a greatest common factor or as a trinomial. Instead, it demonstrates how to factor by grouping terms. The process involves grouping terms, factoring out the greatest common factor from each group, and then solving the problem using the factored terms.
